WARNING
In order to eliminate any risk of damaging the
rotary switch under the steering wheel, observe
the recommendations below:
!Before the steering column and the steering
rack are uncoupled, the steering wheel MUST
be immobilised with the wheels straight for the
duration of the operation using a "steering
wheel locking tool".
!If there is any doubt regarding the correct
alignment of the rotary switch, the steering
wheel must be removed so that the alignment
procedure described in the "AIRBAG" section
can be applied.
REMINDER: in this case, only qualified
personnel who have received training may carry
out the operation.

– the earth strap on the bulkhead,
– the mountings of the air conditioning hoses (if
fitted) on the compressor and the condenser.
NOTE: it is essential to insert plugs in the pipes and on
the compressor to prevent the moisture entering the
circuit.
Remove the upper radiator mountings and attach the
cooling system to the engine.
Fit the engine retaining tool Mot. 1453 ensuring that
the strap is correctly positioned.
Remove the suspended engine mounting cover.Insert a wooden block between the gearbox and the
sub-frame.
Remove the nut (1), then tap it with a copper hammer
to release the suspended engine mounting stud.

REFITTING
Put a drop of RHODORSEAL 5661 at (A) (on either
side of bearing N˚ 1), and at (B) (at the intersection of
the crankshaft closure panel and the cylinder block).
Refit the sump with a new gasket, pre-tightening it to a
torque of 0.8 daN.m, then tighten it finally to a torque
of 1.5 daN.m in the order recommended below.
Fill the engine with oil.

CLEANING
It is very important not to scratch the gasket faces
of any aluminium component.
Use the Décapjoint product to dissolve any part of the
gasket which remains attached.
W ear gloves whilst carrying out the following
operation.
– Apply the product to the parts to be cleaned; wait
about ten minutes, then remove it using a wooden
spatula.
W e must draw your attention to the care which
must be taken during this operation, to prevent
any foreign bodies from being introduced into the
oil ways (ducts located in the cylinder block and in
the cylinder head).
CHECKING THE GASKET FACE
Check for gasket face bow using a straight edge and a
set of shims.
Maximum deformation: 0.05 mm.
No regrinding of the cylinder head is permitted.
Check the cylinder head for cracks.Checking piston protrusion
Clean the piston heads in order to eliminate any traces
of deposits.
Turn the crankshaft in its operating direction, to bring
piston n ° 1 close to TDC.
Fit tool Mot. 252-01 on the piston.
Fit the tool Mot. 251-01 fitted with a gauge on the
pressure plate Mot. 252-01 (the dial gauge measuring
pin being in contact with the cylinder block) and look
for the TDC of the piston.
NOTE: All measurements are to be carried out in the
longitudinal axis of the engine, in order to eliminate
any errors due to tilting of the piston.
Max. piston protrusion: 0.72 ± 0.077 mm

TURBOCHARGING PRESSURE LIMITATION
VALVE (WASTEGATE)
NB: the limitation valve operates in the opposite
way to the usual fittings.
The absence of control pressure causes a
turbocharging pressure limitation.
Check that there are no leaks between the vacuum
pump and the limitation valve.
Checking calibration pressure
Fit on vehicle.
Use a dial gauge which should be positioned at the
end of the wastegate rod (as far as possible in the
wastegate axis).
An underpressure is progressively generated on the
wastegate using a manual vacuum pump.Calibration values
Fitting on the vehicle
When checking the calibration pressure it may be
necessary to adjust the wastegate rod length (A) (if
the pressure is not within tolerance).
This adjustment is made with the turbocharger in
place.
Loosen the lock nut then loosen or tighten the
adjusting nut (B).
Validate the repair in a road test, checking the "RC0
turbocharging limiter valve" parameters and the
"turbocharging pressure" on the diagnostic tools.
